About 'Amp Hours' and 'mAh'

1000mah is the same as 1.0 'Amp Hour', so a cell/pack that is rated at 3300mAh can also be referred to as 3.3Ah.

'Amp hour' ratings are used to describe how much power can be extracted from a battery system over a given timeframe.

So, for example, a 3 Ah battery pack will provide 1 amp continuously for 3 hours, or 3 amps continuously for 1 hour, and so on.

When selecting a battery pack, find out what kind of current (Amps) your application will be drawing, and select an appropriate battery pack.

Note that if you need additional runtime, you can always add an identical pack in parallel (positive to positive, negative to negative) to double your Amp Hour rating, yet keep the same voltage! Add as many packs in parallel as you need to get the Ah desired.

Hooking up multiple battery packs in series (one cell/pack's positive to another's negative, then use the remaining positive and negative for your load), multiplies the voltage, but the overall Ah stays the same.
